Seems to be a bug in the network manager: https://askubuntu.com/questions/461067/is-peap-tls-possible-for-wired-wireless-802-1x

Basically, even if you don't set a CA Certificate, the Network Manager was trying to look for one.

I had to set the variable "system-ca-certs" to "false" manually in the file /etc/NetworkManager/system-connections/name_of_your_network. You would add a line like this (or change it if it was "true"):

system-ca-certs=false
